Description

A kind of sludge drying treatment for reuse system
Technical field
The utility model relates to energy-saving and emission-reduction and technical field of sludge treatment, specifically a kind of sludge drying treatment for reuse system System.
Background technique
During municipal sewage treatment, it is always faced with the problem of how disposing sludge.The side of traditional sludge processing Formula has land use and Sludge landfill.Because sludge is easily corrupt, foul smelling, and contain a small amount of heavy metal ion, at traditional sludge Reason mode easily causes secondary pollution, and irreversible severe can be caused to injure when serious to soil.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of sludge for realizing wet mud zero-emission Drying and other treatment reclaiming system.
In order to achieve the above object, the utility model provides a kind of sludge drying treatment for reuse system, including successively sets Wet mud storehouse, screw pump, solar thermal collector, drying machine, sludge cooler, dewatered sludge storehouse and the boiler set, in which:
The input end of the outlet end connection screw pump in the wet mud storehouse, the outlet end of the screw pump is connected to solar energy collection The input end of hot device, the input end of the outlet end connection drying machine of the solar thermal collector, the outlet end of the drying machine connects The input end of logical sludge cooler, the input end in the outlet end connection dewatered sludge storehouse of the sludge cooler, the dewatered sludge storehouse Outlet end be connected to the boiler;
The top of the drying machine is equipped with steam and is passed through mouth, and the lower part of the drying machine is equipped with condensate outlet:
Through equipped with desalination water pipe in the sludge cooler.
Preferably, the wet mud storehouse is arranged in above the input end of the screw pump.
Preferably, the solar thermal collector is 8000 TF series FS 226-2V of Solar.
The utility model has the following beneficial effects:
1, the utility model carries out dry sludge and fire coal to mix burning, reduces pollution of the sludge to environment, improves The utilization rate of resource and energy;
2, while the utility model improves wet mud temperature as the energy using clean solar energy, drying machine is reduced Steam consumption quantity realizes the utilization of clean energy resource.
3, in thermal power plant's operational process, demineralized water usually first passes around oxygen-eliminating device heating, by low temperature before entering boiler Demineralized water is heated to relevant temperature, can consume a large amount of extracted steam from turbine during heating, and the utility model is dry by high temperature Dry sludge heats demineralized water, reduces steam consumption quantity during oxygen-eliminating device heating demineralized water, and then reduce combustion the consumption of coal, The discharge for reducing the pollutants such as nitrogen oxides, realizes the saving of the energy, reduces operating cost.
This system after the sludge drying generated during municipal sewage treatment, will be sent into power plant boiler to be mixed with fire coal Burning, to reach the requirement of zero-emission.The wet mud that moisture content is 93%~96% is firstly transferred to solar energy collection through screw pump In hot device, the wet mud before entering drying machine is heated using solar thermal collector, improves the temperature of wet mud, and then drop The consumption of steam in low drying machine.High temperature sludge after drying machine is dry enters cooler, and cooling medium is to enter to remove Demineralized water (water at low temperature) before oxygen device improves the water temperature of demineralized water while reducing dry sludge temperature.After reducing temperature Dry sludge is defeated is stored into sludge bin, is delivered in boiler and burns through feeding system.
